My hair is naturally curly and its color is black. Although, I love my hair, and I donât intend to straighten my hair, I am struggling hard to make my hair smooth and happy to touch. I have tried several hair serums and conditioners, including Garnier and Nivea, but nothing stayed for more than two days, and my hair texture was back to the frizzy look. I have even tried a mix of Shea butter and cocoa butter, but it took 3-4 washes to rinse out properly. I have heard about Deva curl hair products as well, but before using it this time, I want to ask from some beauty expert whether it could make my hair smooth without making them greasy. I would be really thankful for your valuable advice.
